I've been married to my wife for three years. With an eye on the future, my mother-in-law decided to live with me and she moved into our house.

I got turned on by my mother-in-law's tight pants ass as she was unpacking her things. I tried to keep my sanity, but my erection didn't go away, so I immediately fucked her! I was so absorbed in pistoning my tall mother-in-law from behind! I ended up cumming inside my mother-in-law with all my thick sperm, and got her pregnant before my wife...
